Radeon R9 280X PowerColor TurboDuo 3GB OC Editionn is a special edition of the high-end Radeon R9 280X. This edition comes with a custom cooling system called "TurboDuo", which reduces the card's temperature under load, significantly and comes overclocked out of the box in the central unit that was increased from 850MHz to 880MHz, while the Boost clock is now of 1030MHz. Benchmarks indicate a very slightly 1% performance boost over the standard edition and so a GeForce GTX 770 is still more powerful.
